# Getting Started

This document describes steps to creating a multiplayer game with Mirror. The process described here is a simplified, higher level version of the actual process for a real game; it doesn’t always work exactly like this, but it provides a basic recipe for the process.

## Script Templates
-   Create new Network Behaviours and other common scripts faster

See [Script Templates](ScriptTemplates.md).

## NetworkManager set-up
-   Add a new game object to the Scene and rename it “NetworkManager”.
-   Add the NetworkManager component to the “NetworkManager” game object.
-   Add the NetworkManagerHUD component to the game object. This provides the default UI for managing the network game state.

See [Using the NetworkManager](../Components/NetworkManager.md).

## Player Prefab
-   Find the Prefab for the player game object in the game, or create a Prefab from the player game object
-   Add the NetworkIdentity component to the player Prefab
-   Set the `playerPrefab` in the NetworkManager’s Spawn Info section to the player Prefab
-   Remove the player game object instance from the Scene if it exists in the Scene

See [Player Objects](../Guides/GameObjects/SpawnPlayer.md) for more information.

## Player movement
-   Add a NetworkTransform component to the player Prefab
-   Check the Client Authority checkbox on the component.
-   Update input and control scripts to respect `isLocalPlayer`
-   Override OnStartLocalPlayer to take control of the Main Camera in the scene for the player.

For example, this script only processes input for the local player:

``` cs
using UnityEngine;
using Mirror;

public class Controls : NetworkBehaviour
{
    void Update()
    {
        if (!isLocalPlayer)
        {
            // exit from update if this is not the local player
            return;
        }

        // handle player input for movement
    }
}
```

## Basic player game state
-   Make scripts that contain important data into NetworkBehaviours instead of MonoBehaviours
-   Make important member variables into SyncVars

See [State Synchronization](../Guides/Sync/index.md).

## Networked actions
-   Make scripts that perform important actions into NetworkBehaviours instead of MonoBehaviours
-   Update functions that perform important player actions to be commands

See [Networked Actions](../Guides/Communications/index.md).

## Non-player game objects

Fix non-player prefabs such as enemies:
-   Add the NetworkIdentify component
-   Add the NetworkTransform component
-   Register spawnable Prefabs with the NetworkManager
-   Update scripts with game state and actions

## Spawners
-   Potentially change spawner scripts to be NetworkBehaviours
-   Modify spawners to only run on the server (use isServer property or the `OnStartServer()` function)
-   Call `NetworkServer.Spawn()` for created game objects

## Spawn positions for players
-   Add a new game object and place it at player’s start location
-   Add the NetworkStartPosition component to the new game object
